• case structure: to run once when the condition is true

  I have a case structure in my program. I use this to count the number of cycles in my experience. I have a knot of feedback (image of the program here attaced) within a box structure. I want the case structure to run only ONCE when the condition is "TRUE". Each "TRUE" represents each cycle. The problem that I'm facing here is that the box structure is permanently running as long as it is 'TRUE' instead of running once and wait for the next 'TRUE '.

  Temporaritly I use a timer inside (as you can see in the picture) to contain the program for the next 'REAL' to come. I hold as by case so I know exactly the time. Is it possible to make the case structure running only once when the condition become ' TRUE and wait for the next "REAL"?  OR is there any other loop that case structure that make this work?

  Hi aneps,

  PtByPt_BooleanCrossing is your friend!

  You really need to work on the analysis/description of your problem: you don't want to run the case as long as the entry is set to TRUE, but you want to run the case at the entrance of the past from FALSE to TRUE!

• procedure to run every month only once if I press the button

  Hi........
  
  I want to run the procedure every month once, if I press the new button in the same month I want displaying the message "executed procedure.
  in fact I used the function procedure when the shutter release button
  
  I wrote this code
  
  Declare
  number of v_months;
  date of T_DATE;
  Start
  v_months: = 0;
  SELECT TO_CHAR (ADD_MONTHS(sysdate,v_months), 'DD-MON-YYYY') in the T_DATE FROM DUAL;
  If T_DATE = sysdate and: CONTROL_1.COST_AFTER_DEPR is not null then
  DEPRECIATE_PKG.main;
  
  elsif: CONTROL. ASSET_GROUP is null then
  fnd_message.set_string ("asset is not available");
  fnd_message. Show();
  raise form_trigger_failure;
  
  elsif: CONTROL_1.COST_AFTER_DEPR = 0 then
  fnd_message.set_string ("' complete depreciation");
  fnd_message. Show();
  raise form_trigger_failure;
  end if;
  
  end;
  
  How can I please give me a solution
  
  Concerning

  Hello

  You should have a database table to store the fact that the procedure was performed for a given month:

  create table t_monthly_procedure
  (
    ddate  date
  )
  

  If the procedure was executed this month then test in your code. Otherwise, you insert a row

  Declare
    ln$dummy pls_integer;
  Begin
    select 1
    into  ln$dummy
    where exists
    ( select 1 from t_monthly_procedure
      where to_char(ddate,'YYYYMM') = to_char(sysdate,'YYYYMM')
    );
    -- found ? --
    -- do nothing or raise a message --
  Exception
    when no_data_found then
     -- nothing done for this month, so insert --
    insert into t_monthly_procedure (ddate) values (sysdate) ;
  End;

• How to open all the text files in a folder at a time so that they cross my VI in good order and the VI should only be run once per file?

  Hello

  I am currently looking to browse hundreds of text files my VI to run the VI once and having labview to open each text file in the order numberical that are contained in a single folder.

  In general, I ran each file one at a time through the VI, hours to browse all text files. I'm wondering if there is a way I can specify a target folder and then open each text file in the target folder and walked through my VI in numberical order (each file is located in the order that is MM_01, MM_02, MM_03...). Currently I open a file at the same time, through "the spreadsheet read", then the index table, and then run through filters etc to get the data I need. I hope there is a way to do it, because he will save days of work.

  Thanks in advance for your help.

  

• Completed the status and run once a sequence

  Hey guys,. In my script, I run a Labiew VI with a button but also continue a button "Cancel". I want this button when press to stop running and go directly to cleaning with a status of "completed." My VI, when the button cancel is pushed to send in the State "Done" chain, but after that I don't know how it interface with Teststand and the property of the step. can someone help me on this topic? second topic: I had a loop and inside I want some sup sequences to run only once, is it a good which can allow me to control this? Thanks in advance!

  Hi pfhenry,

  I'm not sure what you mean by your first point, but I've linked a KB that tells you how you are able to implement a feature similar to the one you described.

  What concerns your second point, you can create a variable for transmitting data of LabVIEW, TestStand, and then tab Module step that calls the VI you can load the value of the VI in the variable you created. I have attached a screenshot showing an implementation of the present.

  Just to clarify your query in a loop, do you have a subsequence TestStand, you want to call once and then ignore the subsequence for each iteration of the loop after the first call?

  Kind regards

• Rule of busyness running ONCE on load

  I have a question, there is a condition of busyness "run when loading" rule, but I noticed that this rule of the bustle runs every time when a button 'go' rule runs once again, is it possible to enforce the rule onle times when the form loads first?

  If you click go to my opinion, that the form is actually to take again with the new selections on the form, which is to take the business rule triggers.

  See you soon

• Time for a while loop to run once

  Hello guys,.

  I want to measure the time for a while loop to run once. There is a piece of code raised. So I just created a simple VI to try, please let me know which is the right way to do it?

  And I wondered, when I run the VI without highlighting the execution, he wouldn't give me a number, maybe it's because the code is simple and really fast? I have to highlight all the time?

  Thank you

  Not quite right.  Both get primitive value time will run at the same time.  use an image sequence to force the order of execution, as shown.  I also brought in the relitve of accuracy seconds vi of VI. LIB\utilities because it depends on the clock of the system rather than the mSec timer accuracy.

  

• Loading and running scripts consecutive in LabVIEW

  Hello

  I would like to start by saying that I am very new to LabVIEW so I apologize for questions that should seem obvious. In addition, when you answer please don't forget I am unfamiliar as I want to be with LabVIEW in general. I recently had a problem on my desktop to add features to a VI preexiting, quite complex. The solution seems to be in scripts. However, a script more 55 loading lines gives an error (is this normal? Is there a way around it?). The problem is fairly easy to break into small pieces, so that the script has been divided into several smaller parts which offer the same functions when run consecutively. After each script execution, the system will take time to process (up to 300 ms, IIRC) and assert a bit ready when you are finished. Using this ready signal as a trigger, I want to run the following script.

  Scripts are read correctly in the program using "niHSDIO Script.vi of Scripture" and can be selected by hardcode the name of the 'script' in 'Configure Script niHSDIO to Generate.vi'. It will run all the scripts successfully of when hardcoded, but trying to call the following script (script names stored in a table and incremented with a while loop) an error is given:

  Error - 1074118651 occurred at niHSDIO Write
  Script.vi
  
  Possible reason(s):
  Driver Status: (Hex 0xBFFA4005) You cannot perform this
  action while the session is in the running state.
  

  At this point, I read quite a bit online and in the documentation to trying to find a way to suspend, interrupt, etc. the State to allow another script load, but I have not been able to understand.

  On the other hand, if there is a way to load a script of arbitrary length, I think that can solve my problem as well. Please let me know what additional information may be required to help solve this, I am sure that I left out all the good bits.

  Thank you in advance,

  Landon

• run a VI in labview with Vision Builder (VBAI)

  HELO,

  I try to use the 'run VI' tool of the vbai (2010). When I lunch the inspection on my PC (with labview 2010) it's ok, but on another PC (without labview), I got an error message (dll is missing).

  I have to copy the data in a specific folder to use this tool?

  You have solutions to solve my problem?

  Thank you

  Ulysses

  If you read the context-sensitive help for the LabVIEW execution step, there will be clear instructions to operate the LLB for Vision Builder AI. I'm not including instructions here because they change slightly depending on the version of the VBAI you are using. However, here are some useful links:

  http://digital.NI.com/public.nsf/allkb/231D87B9D8C3B71A862572D4007EAAF8

  http://forums.NI.com/T5/machine-vision/quot-make-sure-all-of-the-VI-dependencies-including-VI-lib-VI...

  Access the LabVIEW execution step in VBAI, change it, then go to the help > show contextual help (Ctrl-H). In the FAQ tab, there will be a link to describe in detail how to build your LLB for distribution... read carefully and follow the directions.

  Hope this helps,

• Impossible to get "Run once" to do something

  This should be easy.  I was hitting my head all afternoon on that.

  VC 2.5 ESX 3.5

  I have a Windows 2003 server model that we deploy.  I would like to issue a command "Run once".  Nothing seems to work.

  I tried the following:

  Regedit /s /d "HKEY_LOCAL_MACHINE\SOFTWARE\Network Associates\ePolicy Orchestrator\Agent\AgentGUID"

  Regedit /s /d "HKEY_LOCAL_MACHINE\SOFTWARE\Network Associates\ePolicy Orchestrator\Agent\MACADDRESS"

  I tried to put it in a file bat and use:

  C:\Utilities\RunOnce.bat & gt; C:\Utilities\RunOnce.out.txt 2 & gt; & 1

  I prefer the .bat file method would work.  I have tried many variations and other very simple commands.  This very simple concept I'm missing here?  Is there a log somewhere that I can use to see if there are errors?

• RAM preview will not stop running once?

  I'm obviously trying to RAM Preview a project and for some reason any now when I run the RAM Preview... it will run through... and once it gets to the end, he makes a loop and performs a loop and loops. Not normally a big problem since I was usually able to stop with one of the other Preview button or a button ESC or something. For some reason any now... nothing that I don't constantly RAM Preview. The only thing I can do is a ctrl + alt + delete to stop it (not really closing After Effects, just the simple fact to bring up Task Manager to stop it).  Any ideas of what I could have pushed, what could happen?

  Well... seems to have fixed itself, I don't know what happened. Thanks anyway.

• We had a problem with the sending of an email, he said to send later. My boss began pressing the buttons, and there is now no button send in the window to compose a. Help

  Send no button when composing an email

  When the Send button changes to send later, he indicates that Thunderbird is in offline mode.
  It is taken offline for several reasons. You said that he or she has detected a loss of network connection. Happens frequently on a laptop because the NICs tend to shut down when the laptop goes to sleep.
  There is an indicator online / offline in the lower left corner of the window of Thunderbird. It looks like 2 computer screens. When there is a red cross on Thunderbird is in offline mode.
  You can click on this icon to change state. I suggest you do this next time instead of blindly clicking on buttons that you don't remember.

  The Send button is the Composition toolbar in the window of writing.
  Open a window of writing.
  If you've managed to disable the also menu bar press the alt key to bring up.
  The menu bar, select View-Toolbars and relight the toolbars.

• Is there a quick delete button that can be added next to emails?

  During playback by emails in Thunderbird there are emails that I know I want to read and remove enough quickly without having to click on the email itself.

  What I'm looking for, it's a quick delete button similar to the 'star' button that can be added as a column. I would like a button which is located near the titles of message in the e-mail pane that allows me to quickly delete messages.

  Microsoft Outlook (windows mail) has something like that on all messages and I would if this feature could be reproduced in Thunderbird.

  It's not Outlook and there is not this button. Right click - Delete the Message
